Denios specializes in innovative spill control and containment solutions tailored for various industrial needs. Their latest products include automatic and manual doorway spill barriers, as well as the Hazberm modular containment system, designed to efficiently manage large spills and floods while complying with safety regulations. These advanced systems are crucial for preventing environmental contamination and limiting cleanup costs associated with hazardous materials.

1. DENIOS prides itself on leading the spill
control and containment industry in product
development.
Spill containment or Secondary Containment
systems are generally conceived to hold a
pre-defined volume of liquid in a containment or
spill sump sized for the specific volume of product
being stored. These products confine a spill in
the sump to prevent the spill from spreading.
Many situations do not lend themselves to
common secondary containment equipment.
Processing or warehousing often involve larger
volumes or areas than can be practically housed
in a hazmat enclosure. In addition, what about
damage to facilities from outside floodwaters?
What options are there for containing larger
spills or floods that threaten wide areas?
OSHA and EPA Regulations require that all
releases be contained and that the flow of
chemicals and / or sprinkler water be prevented
from migrating into drains, sewers or the
environment. Such large volume spills can prove
to be catastrophic in scope and expenses involving
reclamation, repair and monetary fines.
Recent developments have led us to combine
several of our newest technologies into a new
family of products under the LASC™ trade name.
DENIOS is your best partner for analyzing and
solving your Large Area Spill Containment issues.
Large Area Spill Containment
Automatic Doorway Spill Barriers quickly seal off a room, preventing any spill from contaminating other
parts of your plant. The ADSB operates without any power assist and lays flat until triggered by a spill.
The HazBerm is a system of polymer concrete
segments which easily assemble to form a leak
proof, chemical and fire resistant, temporary
chemical storage area.
Manual doorway spill barriers are great for low
traffic areas. The door easily lifts out for access
to the sealed area, otherwise the door is
normally in place.
FM Approved Doorway Flood Barriers guard against flash floods from entering facilities. Like the ADSB,
they operate without any power assist and lay flat when not in use, allowing normal traffic flow.

3. In cases of catastrophic spills or sprinkler
releases, containing the spill to a single
room or area can limit the costs associated
with clean-up or facility damage.
DENIOS Automatic Doorway Spill Barriers provide
the protection to contain those large spills by
closing off any doorway or opening in the affected
room at the first sign of flowing liquids.
Federal Regulations along with Local Jurisdictions
require that sprinkler water in combination with
regulated or hazardous materials be prevented
from being released into the environment via
sewers, streams, or ground contamination.
When a release occurs, fines and clean-up costs
can be staggering.
NFPA-30 9.13.3
Curbs, scuppers, special drains, or other suitable
means shall be provided to prevent the flow of
liquids under emergency conditions into adjacent
building areas.
IFC-2704.2.2.3 (2009)
Secondary containment for indoor storage
areas shall be designed to contain a spill from
the largest vessel plus the design flow volume
of fire-protection water calculated to discharge
from the fire-extinguishing system over the
minimum required system design area or area
of the room… for a period of 20 minutes.
OSHA 1910.106 (e) (3) (iv) (a)
Emergency drainage systems shall be provided
to direct flammable or combustible liquid leakage
and fire protection water to a safe location.
This may require curbs, scuppers, or special
drainage systems to control the spread of fire.
OSHA 1910.106 (d) (4) (i)
Openings to other rooms or buildings shall be
provided with non-combustible liquid-tight raised
sills or ramps at least 4” in height.
Automatic Doorway Spill Barriers
Barriers prevent spills from reaching storm drains or contaminating ground water
Combine with curbing to effectively cut off and contain liquid storage areas.

6. The barrier is designed for both interior
and exterior storage applications.
Manual Doorway Spill and Flood Barriers
The latest DENIOS innovation!
Introducing our new line of Manual
Spill and Flood Barriers for Doorways.
Barriers clamp securely into preset piers mounted
on either side of the opening.
Designed to contain spills, leaks, and / or sprinkler
water releases. By sealing off doorways or other
openings, liquids are prevented from spreading
beyond the immediate room or area.
Barriers may also be used on the exterior of
doorways to prevent high water from storms
or floods from entering critical areas and
damaging, expensive equipment or inventory.
On-site installation is easily accomplished in
new or existing facilities using the step-by-step
installation instructions provided.
Chemical-resistant gaskets maintain a tight
seal in both hot and cold conditions
Rigid design withstands extreme
temperatures during a fire
Unique clamping mechanism secures the
barrier in place between piers
Eliminates need for ramps / berms at
doorways or other openings
Deploys in Seconds!
Barrier piers are mounted on both sides of the
doorway, allowing normal traffic when the
barrier is not deployed.
At the first sign of an incident the barrier is
lowered into position.
Within seconds the doorway is secured against
flowing liquids.
Note: Other heights widths available!
When open, store the barrier close to
the mounting piers for quick, easy deployment
in the event of a spill.
